Burners ® Beckett BioHeat BioHeat® ready! READY

Beckett is pleased to announce we will warranty our burners for use with BioHeat blends, up to B5, meeting the fuels standards below.

Fuel standards: Know your fuel! The biggest cause of problems is off-spec blend stocks. B5 fuels must be made from the following materials: • 5% biodiesel (B100) meeting the requirements of ASTM D6751. (D6751 is the standard specification for Biodiesel Fuel Blend Stock for Bioheat blends.) • 95% petroleum fuel (No. 2 or No. 1) meeting the requirements of ASTM D396. (D396 is the standard specification for Fuel Oils.) • Use suppliers that are BQ-9000 certified where possible. (BQ-9000 is a Quality Assurance system for certifying, distributing, blending, and maintaining the quality of biodiesel / bioheat products.) • Insist on certification – certificates for the base fuel, the biodiesel blend stock and the finished blend.

Beckett also recommends the following safeguards: Additives: Yellow metals: Stability leads the list of things to watch for. During storage Copper and its alloys (brasses, bronzes) are known to and handling, fuels may react with their surroundings and cause (catalyze) reactions with all organic materials, with materials in their environment to form undesirable including petroleum fuels, and more so with biodiesel. by-products that can interfere with proper operation.

If this is necessary, there are a number of actions that can be taken: Filtration: • Two-pipe systems should be converted to single-pipe.

Biofuels-made from plant or animal oils- have the potential to offer many benefits for the country, for oilheat dealers and for homeowners. They include: • Expanding the fuel supply for transportation and heating - and a resulting reduction in price pressure. • Reducing our dependency on international sources of petroleum. • Growing crops for biofuel production ‘recycles’ carbon back into the plant material, eliminating an environmental objection to fossil fuels.

Exactly what is a Biofuel? What are the next steps in getting biodiesel “Biofuel” is a broad term for a variety of fuels derived approved? from living sources. One distinction is between: The clearest path for full biodiesel approval in burner systems is to revise ASTM D396 to include Biodiesel – products typically derived from “oily” biodiesel blends. Industry groups have completed products such as soybeans (US) or rapeseed (Europe) much testing under a UL fact-finding investigation, that behave much like middle distillate products like and found that they yielded acceptable results from heating oil and diesel. They are made by a chemical a combustion standpoint. However, a number process and purified before being sold. of questions remain about the compatibility of both B5 blends and neat B100 blend stock with Ethanol – products derived from sources such as materials commonly found in oil burner systems. sugar cane, corn and grasses that are converted into gasoline-like products by a distillation process. What research is planned to further the case that B5 should be included in ASTM D396? However, there are many other distinctions, such as Additional investigation above and beyond source, previous use and the percentage blends with the recently completed fact-finding study is traditional petroleum products. being discussed, and would include a more comprehensive investigation of biofuels from What about blends of biodiesel and petroleum a variety of source materials. Testing could fuels? include compatibility with a wider cross-section You will hear about B5, B20, or B100. The number of materials from oilheat systems and basic B5 represents the percentage of biodiesel in a blend of stability (storage life). Ideally, the investigation petroleum. For example, B5 is a blend of 5% biodiesel would break the oilheat system into specific, and 95% standard heating oil. manageable blocks so that any next steps could be defined. Is biofuel fully approved for use in heating systems? What is Beckett doing to help? No. Underwriters Laboratories (UL) requires that fuel Beckett is actively involved in many aspects of the for oil heaters comply with ASTM D396, which does not approval and testing process to help develop safe, allow for the use of biodiesel blends. Beckett and other reliable standards for biodiesel blends. leaders in the heating industry are working to amend ASTM D396 to include biodiesel blends up to 5% (B5).
